一个类似电商的时间预约功能，供大家参考，具体内容如下

1 .概述

我们在学习微信小程序或者做项目时，应该会遇到需要时间预约功能情况，那么这个时间预约功能我们应该怎么编写呢？于是就做了一个类似电商的时间预约功能，觉得有用，就独立出来成了个小插件，今天我们就分享这样的小教程。希望对大家有所帮助。

不多说了，上图来啦！

2. wxml

<!--pages/orderTime/index.wxml-->
<view class='containt'>
 <scroll-view class="scroll-view_H" scroll-x>
  <view class='list' style='width:{{ width }}rpx'>
   <view bindtap="select" wx:for="{{ calendar }}" wx:for-item="item" wx:for-index="index" data-index="{{ index }}" class='listItem {{index==currentIndex? "current":""}}' wx:key='' data-date="{{ item.date}}">
    <text class='name'>{{ item.week }}</text>
    <text class='date'>{{ item.date }}</text>
   </view>
  </view>
 </scroll-view>
 <view class='time'>
  <view wx:for="{{ timeArr }}" wx:for-item="timeItem" wx:for-index="timeIndex" data-Tindex="{{ timeIndex }}" data-time="{{ timeItem.time}}" bindtap='selectTime' class='listItem {{ currentTime==timeIndex? "current":"" }}' wx:key=''>
   <text>{{ timeItem.time }}</text>
   <text>{{ timeItem.status }}</text>
  </view>
 </view>
 <view class='operate'>
  <button class='del'>删除</button>
  <button class='save'>保存</button>
 </view>
</view>
